Concern about the higher speeds of foreign boats had prompted the Admiralty to order new destroyers capable of 30 knots (56 km/h; 35 mph), rather than the 27-knot (50 km/h; 31 mph) requirement which had been standard. The boats were not able to make this speed in bad weather, where they were usually wet and uncomfortable with cramped crew quarters, but they proved their toughness in serving in the Great War, despite being twenty years old. Thanks to their watertight bulkheads, their thin plating and light structure was able to take a great deal of damage and remain afloat, although their plates buckled easily affecting their handling. Myrmidon was sunk after a collision in 1917, while Syren served through the war and was broken up after the end of hostilities.

The ships were fitted with Reed boilers which generated around 6,200 horsepower (4,600 kW). They were armed with the standard 12-pounder gun and two torpedo tubes and carried a complement of 63 officers and men. Ships of this type bore four funnels and were designated B-class destroyers after a reorganisation in 1913. These particular ships had a special form of funnel cap fitted which was designed to prevent sea water entering the space between the funnel uptake and outer casing.
